Contribution Of Retrotransposons To Breast Cancer Malignancy, Isaac D. Raplee

USF Tampa Graduate Theses and Dissertations

The components contributing to cancer progression, especially the transition from early to invasive are unknown. Consequently, the biological reasons are unclear as to why some patients diagnosed with atypia and ductal carcinoma in situ (DCIS) never progress into invasive breast cancer. The “one gene at a time” approach does not sufficiently predict progression. To elucidate the early stage progression to invasive ductal cancer, expression signature of transcripts and transposable elements in micropunched samples of formalin-fixed, paraffin embedded (FFPE) tissue was conducted. A bioinformatics pipeline to analyze poor quality, short reads (>36 nts) from RNA-Seq data was created to compare …

Regeneration Of Trace Metals During Phytoplankton Decay: An Experimental Study, Adrienne P. Hollister

USF Tampa Graduate Theses and Dissertations

Trace metals act as important nutrients, and sometimes toxins, to phytoplankton and other marine microorganisms. When phytoplankton decay, the elements in their cells are released back into the water column through regeneration (also referred to as remineralization), one of the processes responsible for governing concentrations of dissolved trace metals and macronutrients in depth profiles. In order to experimentally study regeneration, controlled experimental incubations of mixed phytoplankton assemblages from the Gulf of Mexico (GoM) and monocultures of the diatom Pseudo-nitzschia dolorosa and the dinoflagellate Karenia brevis were placed in the dark and monitored as they decayed with naturally present bacteria.

Making Sense At The Margins: Describing Narratives On Food Insecurity Through Hip-Hop, Lemuel Scott

USF Tampa Graduate Theses and Dissertations

Neoliberalism is the contemporary political and economic thought that promotes ideas of private property, individualism, and market logic as key to advancing humanity. Scholars generally link neoliberalism to poverty from a broad perspective, but few have explored how it specifically impacts food insecurity. Globally, many people impacted by poverty also experience food insecurity. Hip-hop is important to resistance and fostering my critical worldview. Existing literature primarily describes hip-hop as a critical tool giving expression to people living at the margins. However, there is a need for hip-hop to be used more often as resistance by artists doing research. First, this …

Dormancy In The Amphistegina Gibbosa Holobiont: Ecological And Evolutionary Implications For The Foraminifera, Benjamin J. Ross

USF Tampa Graduate Theses and Dissertations

Dormancy, a state of severely decreased or suspended metabolism, is a widespread survival strategy in nature. In the Foraminifera, one of the most studied groups of marine organisms, its presence had been suggested by circumstantial evidence, but rarely studied directly until recently. Despite the lack of research, stressor-induced dormancy can significantly alter the way in which foraminiferal ecology is understood, especially in marginal environments. In this dissertation, I reviewed the evidence for dormancy in the foraminiferal literature, concluding that evidence for dormancy is widespread across the Phylum. I then explored the role of dormancy in the survival of the diatom-bearing …

Investigating The Role Of The Rna Binding Protein Lin28 In The Human Placenta: Implications For Preeclampsia, John Canfield

USF Tampa Graduate Theses and Dissertations

An essential event during early pregnancy is the invasion of trophoblasts into the maternal decidua, which is necessary for proper implantation and establishment of maternal-fetal interface and ultimately allows for proper nutrient exchange and immunological tolerance of the growing fetus. For this invasion to occur, cells originating from the trophectoderm undergo an epithelial to mesenchymal transition to become invasive extravillous trophoblasts and begin invading the uterine decidual tissue. Through the secretion of matrix metalloproteinases and through interactions with many cytokines and cell-adhesion molecules, this well-orchestrated process of trophoblast invasion results in extensive remodeling of the maternal spiral vasculature by the …

A Longitudinal Exploration Of Drive For Leanness: Potential Uniqueness, Sex Neutrality, Adaptive Nature, And Sociocultural Fit, Brittany Lang

USF Tampa Graduate Theses and Dissertations

Historically disordered eating research has been gendered with models focusing on women’s pursuit of a thin ideal, as well as men’s attempts to obtain a muscular ideal. The motivations to achieve these ideals are called the drive for thinness (DT) and drive for muscularity (DM). More recently, a cultural shift has been noted in that ideal bodies are converging across sexes to a lean ideal, with the associated motivation being labeled the drive for leanness (DL). As DL is a nascent construct, little is known about its relationships with DT and DM, or if it predicts or is predicted by …
